Prof. Weina, University of New South Wales, Australia? Sahajwara has developed a new method of using waste rubber and plastic for steel production - polymer injection process. Handan Corbel tube It can not only greatly reduce the environmental pollution caused by waste rubber and waste plastics, but also effectively reduce the cost of steel production. Waste rubber and plastic contain a lot of carbon. Waste rubber and plastic are put into the electric arc furnace as substitutes for carbon element. The carbon originally locked in the waste plastic hose will react at ultra-high temperature and burn with coal to become clean fuel, thus reducing greenhouse gas emissions, At the same time, it also alleviates the environmental pollution caused by using them as landfill. The advantage of polymer injection process is that by injecting polymer and coke or anthracite rubber tube mixture, the volume of slag can be increased and the foaming degree can be increased, which can extend the arc length, increase the heat transfer from the arc to steel, reduce the heat loss through the slag and side walls, and thus improve the power efficiency. This reduces power consumption by about 3%. For every 1 ton of steel, about 24% of the cost comes from the cost of electricity. After polymer injection technology is adopted, each furnace of steel is, Corbel tube Where can I find it? The average total amount of carbon injected can be reduced by 10%~20%. In addition, the potential price of polymer is lower than that of coke, and the total cost of carbon injection can be saved by 15%~35%.
1. The use of protection cannot be ignored: the long-term use of high-pressure sand blasting hose joints at home usually does not cause concern, but excessive use and improper protection also buried the hidden danger of joint cracking to a certain extent. It is understood that the service life of the joint is usually 200000 times, and it should be replaced after long-term use. When using the side, Corbel tube Where can I find it? Care should be taken to close and open as gently as possible and not to rotate the knob of the hose connector repeatedly. 2. Differentiation of quality can be based on standard evidence collection. It is understood that it is still difficult to determine the cause of joint cracking. At present, the National Bureau of Technology and Quality Supervision has issued recommendations for sealing nozzles and hose specifications. These two specifications perfectly adjust the quality specification target of connectors and hoses. Consumers can go to the quality inspection department to check the torsional strength of the connecting hose, the tightness of the connecting spool and the strength of the connecting materials. If the content of standard rules cannot be met, it will be attributed to quality problems, which can serve as a strong basis for expression. 3. The appearance of hose connector is difficult to distinguish between good and bad. In order to pursue profits and reduce costs, many manufacturers currently use selected cast iron (easy to rust) and zinc alloy (non anti-corrosion) as materials to produce high-pressure sand blasting hose joints, which causes product quality problems. It is understood that the quality of connectors and hoses is not up to standard, Handan Corbel tube The strength function and sealing function of high-pressure sand blasting hose joints are not up to standard due to problems such as materials and wall thickness, which should be paid attention to by consumers.
I, production Corbel tube Quantitative display of quality. In the evaluation plan prepared by the Ministry of Health and Social Insurance for the medical and health system, some indicators were put forward for the service quality of the hospital, such as the number of deaths before and after the operation, the number of unplanned rehospitalization, the infection rate of patients in the hospital, and the immunization rate. It can be seen that the quantification of quality is to reflect the quality of things through a series of quantitative analysis and synthesis. Sand blasting hose enterprises use public opinion polls to measure benefits and service quality. Since the purpose of administrative activities is to meet the needs of society or the public, the best way to measure the social effect and quality is to face the service objects, understand their evaluation and their satisfaction. Although popular, public opinion polls also have limitations, such as high cost, which is difficult to be accurate and reliable due to the influence of public judgment. In addition, the satisfaction of beneficiaries does not answer the question - is this service provided to those who need it most? III, Corbel tube Where can I find it? Administrative departments and public service institutions with single business nature. For those departments that have applied the quality assurance system, their performance evaluation only pays attention to efficiency and economy.
high pressure production Corbel tube There are many uses. When we choose products, understanding the basis for selecting production materials for high-pressure sandblasting hose will help us to select more suitable high-pressure sandblasting hose. The following small series will briefly introduce it to you: 1. The working environment of the product comes from the working environment of high-pressure sand blasting hose, such as outdoor environment, mechanical equipment, surface, etc. Considering these factors comprehensively, anti-aging and wear resistance shall be considered when selecting materials. 2. Function: From the performance of high-pressure hose, the main function of tubing is oil resistance, so the oil resistant material of material composition is the key. The quality must be well controlled. Among the oil pipes, there are also high-pressure oil pipe series, which is what we often call high-pressure rubber sandblasting hose. Pressure is necessary, so the steel wire reinforcement layer is used as the pressure bearing layer. This wire must be selected. 3. Economic indicators: from the economic indicators of high-pressure sand blasting hose, the economy is to spend less and produce more. The stability of the material, the rationality of the formula and the cost performance ratio of the formula must be considered. 4. Safety factors: consider the safety factors of high-pressure sand blasting hose, the requirements of normal working environment of oil pipe, and the effects of anti-static, flame retardant and normal pressure resistance. Talking about materials in this field, Corbel tube Where can I find it? It is necessary to select suitable materials. Some important materials involving various requirements are particularly important. 5. Manufacturing technology: from the perspective of manufacturing process of high-pressure sand blasting hose, manufacturing economy, product stability and feasibility of continuous production are mainly considered. Materials shall meet production requirements as far as possible.
As production Corbel tube As an important part of sand blasting machinery, its safety plays a vital role in the safety of equipment operation. The following will briefly analyze the precautions in the use of high-pressure sandblasting pipe: I. Pipe inner diameter: inner diameter of high-pressure sandblasting pipe. 2、 Attention shall be paid to the following items in the use and design of high-pressure sandblasting pipe: 1. The bending radius of high-pressure sandblasting pipe shall not be too small, and generally shall not be less than the value specified in the assembly technology of high-pressure sandblasting pipe. The joint between the high-pressure sandblasting pipe assembly and the pipe joint shall have a straight section, and its length shall not be less than twice the outer diameter of the pipe. 2. The length of high-pressure rubber hose assembly shall consider that the high-pressure rubber hose will shrink and deform after introducing pressure oil. Generally speaking, the shrinkage rate is 3~4 times of the pipe length. When installing the high-pressure rubber hose assembly, it is not allowed to bear tension. 3. During installation, the high-pressure sandblasting pipe assembly shall be free from torsional deformation. Corbel tube Where can I find it? The connecting shaft of shall be placed in the moving plane as far as possible to avoid damaging the high-pressure sandblasting pipe when both ends move with each other. 4. High pressure resistant sand blasting pipe shall avoid contact and friction with mechanical sharp corners to avoid damaging the pipe. Safety measures: to ensure the safe and reliable use of high-pressure sandblasting pipe assembly.
