The safety requirements of casting machinery include the reinforcement and maintenance of the top of the plant of the machinery casting enterprise, the inspection and maintenance of equipment and facilities, the consumption of electricity, the prevention of the influence of factors such as night and other factors to save costs, and the prevention of high-altitude fall, collapse and other accidents. In addition, enterprises should strengthen the implementation of risk control measures and hidden danger investigation and management in the smelting process in accordance with relevant standards. In the pouring operation, the safety technical requirements of the pouring operation include three processes: encapsulation, pouring and cooling, of which the pouring ladle should be checked whether it meets the requirements before pouring

The raw materials of refractory materials are mainly natural minerals, such as refractory clay, high bauxite, silica, chromium ore, magnesite and so on. In addition, there are some special raw materials, such as aluminum silicate refractory fiber, magnesia and alumina clinker. After processing, melting and other processes, these raw materials can be made into a variety of different forms of refractory materials, which are used in the manufacture of high-temperature furnace linings, furnace doors, furnace covers and other components.

The recycling and utilization of aluminum alloy is one of the important technologies in the field of environmental protection. It is understood that most of the recycled aluminum waste is remelted in the furnace, cast as recycled aluminum ingots, or a small part of the waste aluminum is directly reformed and utilized. At the same time of the rapid development of recycled aluminum industry, it is also faced with many challenges such as how to improve the recovery rate of scrap aluminum, improve recycled aluminum, strengthen the utilization of recycled aluminum, and improve the utilization of recycled aluminum.
Aluminum recycling not only protects the environment, but also improves economic efficiency. The aluminum recycling value chain spans different and geographic regions, creating a chain where the end product, recycled aluminum, creates value [3]. Therefore, strengthening the research and promotion of regeneration and utilization technology is of great significance for realizing the recycling of resources and building a green and low-carbon society.

Industrial furnace is one of the commonly used equipment in industrial production, mainly used for heating, melting, heat treatment and other processes. According to the search results, the application of industrial furnaces is very wide, including but not limited to the following aspects:

First of all, industrial furnaces can be used for the heating and melting of various materials, such as the melting and casting of metals such as steel, copper and aluminum, as well as the heating treatment of materials such as plastics and ceramics.

Secondly, industrial furnaces can also be used for heat treatment and surface heat treatment, such as quenching, tempering, annealing and other processes, as well as surface heat treatment and surface treatment of various metal parts.

In addition, industrial furnaces can also be used for the control and automation of heat treatment equipment, such as temperature control, atmosphere control, flow control, etc.

Finally, industrial furnaces can also be applied to the research and development of various heat treatment equipment and heat treatment processes, such as the research and development of new materials and the optimization of heat treatment processes.

In short, industrial furnace plays an important role in industrial production, its application range is wide, and the application prospect is also very broad.

Cutting machine safety operating procedures refer to a series of safety standards and operating specifications that must be observed when using cutting machines. According to the search results, safe operation procedures for cutting machines include:

1. General cutting machine safe operating procedures must be followed. Start the laser in strict accordance with the laser program.
2. After training, the operator is familiar with the structure and performance of the equipment, and master the knowledge of the operating system.
3. Wear labor protective equipment according to the regulations, and wear protective glasses near the laser beam that meet the regulations.
4. Do not process a material before it is clear whether it can be irradiated or heated with a laser to avoid the potential danger of smoke and vapor.
5. When the equipment is in operation, the operator shall not leave the post or entrust the person to manage, if it is really necessary to leave, the power switch should be shut down.
6. Keep fire extinguishers within easy reach; Turn off the laser or optical brake when not processing; Do not place paper, cloth, or other flammable materials near an unprotected laser beam.
7. When anomalies are found during processing, they should be stopped immediately and eliminated in time.
8. The above is the main content of the safety operation procedures of the cutting machine. In the operation of the cutting machine, these specifications must be carefully observed to ensure the safety of personnel and equipment.

Rolling mill is a kind of equipment for processing metal, according to the rolling method, the number of rolls, rolling materials, etc., can be divided into many. Among them, the common rolling mills include hot strip rolling mill, bar rolling mill, rolling mill bearing and so on. Hot strip rolling mill includes rough rolling work roll, vertical roll, F1 to F3 finishing rolling work roll, F4 to F7 finishing rolling work roll, support roll and complete machine work roll, of which the two rough rolling mill work roll should contain chromium cast steel or forged steel roll. The types of bar machines include closed two-high mill, short stress line mill, cantilever roller mill, in which closed two-high mill is mainly Morgan type and Simak type, short stress line mill mainly introduced models are Danieli type and Premini, cantilever roller mill is only Neli development. Rolling mill bearings include self-aligning roller bearings, which have two sets of self-aligning roller bearings installed on the same roll neck and one set of self-aligning roller bearings installed together with another roll neck. The former basically meets the production conditions at that time, while the latter has the advantages of high rolling speed, finished product accuracy and strict control of roll axial clearance.
