Embodiment Construction

[0021] The present invention will be further described below:

[0022] The invention consists of fluorite powder, broken glass, lime, borax, cryolite powder and perlite.

[0023] Further, the particle size of the fluorite powder is 140 mesh, the particle size of the cullet is 140 mesh, the particle size of the lime is 70 mesh, the particle size of the borax is 140 mesh, the particle size of the cryolite powder is 200 mesh, and the particle size of the perlite is 140 mesh. It is 70 / 140 mesh.

[0024] Further, the ratio of the fluorite powder is 0% to 5%, the ratio of the cullet is 0% to 5%, the ratio of the lime is 0% to 5%, and the ratio of the borax is 0% to 2%. %, the proportion of the cryolite powder is 0% to 3%, and the proportion of the perlite is 80% to 85%. ,

[0025] Manufacturing process of the present invention comprises the following steps:

[0026] ① Semi-mature the perlite first, then crush and sieve the perlite into a particle size of 70 / 140 mesh;

[0027] ②...

Abstract

The invention discloses an efficient molten iron purifying and deslagging covering agent for high-intensity gray cast iron and ductile cast iron. The efficient molten iron purifying and deslagging covering agent is prepared from fluorite powder, cullet, lime, borax, cryolite powder and perlite. Compared with the prior art, the efficient molten iron purifying and deslagging covering agent disclosed by the invention has the advantages that the raw materials are convenient to purchase; the production process is simple, and the equipment investment is low; molten iron is added to be in contact with the covering agent to realize quick bulking melting, and the covering agent can be automatically spread to interact with slag on the surface of the molten iron, thus forming a slag gathering layer, and furnace slag is easy to remove; the product does not contain a component which may pollute the molten iron, can easily absorb gas separated from the molten iron and capture inclusions and oxides in the molten iron, is odorless and pollution-free during use, and belongs to an environment-friendly product; gas absorption caused by heat dissipation of the molten iron is reduced, and the heat preservation effect is good; the efficient molten iron purifying and deslagging covering agent belongs to an efficient energy-saving product.

Description

technical field [0001] The invention relates to a cast iron auxiliary agent, in particular to a high-efficiency molten iron purifying slag-removing covering agent for high-strength gray cast iron and ductile iron. Background technique [0002] High-strength ash is used in cast iron auto parts, hydraulic parts, machine tool parts, motor castings and ductile iron auto parts, mold parts, hydraulic parts, high-speed iron parts and low-temperature ductile iron for wind power melting process, molten iron covering purification and slag removal, and ladle Cover insulation in. It is suitable for smelting in 0.5t~30t intermediate frequency furnace. In the prior art, during the process of casting iron, slag adheres to the furnace, which is difficult to remove, has a strong smell during use, and is not environmentally friendly. Therefore, there is room for improvement. Contents of the invention [0003] The object of the present invention is to provide a high-efficiency hot metal pu...
