Abstract

The invention discloses a preparation method of a releasing agent for an iron casting machine, belonging to the technical field of releasing agents for metallurgy casting. The preparation method disclosed by the invention comprises the following steps of: weighing 15-17 parts of soybean oil and 17-19 parts of bentonite according to the mass ratio, and uniformly mixing to obtain a mixture A; weighing 20-25 parts of blast sludge, 10-13 parts of electric dust-removing ash of a sintering machine head and 16-23 parts of dust-removing ash of a bunker in the front of a furnace according to the mass ratio, uniformly mixing, and roasting at 600-800 DEG C for 30-35 min to obtain a mixture B; weighing 5-7 parts of limestone, 9-10 parts of alumina, 11-15 parts of dolomite, 3-5 parts of zirconia and 7-8 parts of iron red epoxy ester primer according to the mass ratio, adding the above components into the mixture B and mixing uniformly so as to obtain a mixture C; mixing the mixture C and the mixture A to obtain a mixture D; and mixing the mixture D and 800-1000 parts of water, and uniformly stirring to obtain the releasing agent. The releasing agent prepared by the invention can be effectively attached to the inside surface of a casting mould, therefore, the surface of a cast iron ingot is smooth.

Description

technical field [0001] The invention relates to the technical field of release agents for metallurgical casting, and more specifically, to a preparation method of release agents for cast iron machines. Background technique [0002] The iron casting machine is a device for continuously casting molten iron into iron blocks. It is a circular chain belt with many iron molds and chain plates tilted upwards. It revolves around the star-shaped large gears at the upper and lower ends. The gear is a transmission wheel driven by a motor, and the star-shaped large gear at the lower end is a guide wheel, and its bearing position can be moved to adjust the tightness of the chain belt. According to the fixed situation of the roller, the cast iron machine is divided into a fixed roller cast iron machine and a movable roller cast iron machine. The process of cast iron machine is that the locomotive transports the molten iron tank car or mixed iron car loaded with molten iron from the blast...
