Manufacturing process of energy-saving and environment-friendly metal pressing block

Abstract

The invention discloses a manufacturing process of an energy-saving and environment-friendly metal pressing block, and relates to the technical field of metal product manufacturing. The manufacturing process of the energy-saving and environment-friendly metal pressing block comprises the following steps that S1, a heating furnace is erected, and the specific requirements of the heating furnace are as follows: S11, a 310S stainless steel material is adopted as a material of a heating furnace pipe; according to the manufacturing process of the energy-saving and environment-friendly metal pressing block, the strength of a product is well guaranteed by limiting the density of the product, meanwhile, heat preservation cotton is used for replacing refractory bricks in the prior art, the heating furnace pipe made of 310S stainless steel materials is used, the length of the high-temperature furnace of the heating furnace is only 16 m, and compared with an existing furnace body with the length of 40 m, the floor space and the manufacturing costs are greatly reduced. Compared with the prior art that the raw materials are heated to 1500 DEG C to melt the raw materials and then slag-iron separation is carried out, only 900 DEG C is needed, it can be guaranteed that no steel slag exists in the raw materials without melting the raw materials, energy consumption is reduced, and the pollution degree to the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of metal product manufacturing, in particular to an energy-saving and environment-friendly manufacturing process of metal briquettes. Background technique [0002] Metal briquetting is a kind of steel product, generally used for the counterweight of large-scale equipment, in the prior art, the manufacture of steel product is generally divided into two ways of steel slag pressing and steel plate cutting. [0003] Among them, the steel plate cutting manufacturing method has high raw material cost and low raw material utilization rate, which is likely to have an impact on the environment. [0004] The existing steel slag pressing manufacturing method uses 40m refractory bricks as the furnace body to directly heat the steel slag, which occupies a large area. At the same time, steel slag and iron blocks need to be heated to 1500°C as raw materials until they melt, and the energy consumption is relatively high. H...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an energy-saving and environment-friendly manufacturing process of metal briquettes, which solves the problem that in the prior art, the manufacture of iron and steel products is generally divided into two methods: steel slag pressing and steel plate cutting. The raw material cost of the manufacturing method is high, and the utilization rate of raw materials is low, which is easy to affect the environment. The existing steel slag pressing manufacturing method uses 40m refractory bricks as the furnace body to directly heat the steel slag, which occupies a large area At the same time, it is necessary to heat steel slag and iron block as raw materials to 1500°C until they are melted, so the energy consumption is relatively high, the degree of pollution to the environment is large, and the overall cost is high.
