Embodiment 1

[0040] A kind of demoulding agent for cast iron machine of the present embodiment, its component and content are as follows: blast furnace gas mud 20kg, sintering machine head electrostatic precipitator ash 10kg, mine trough dust removal ash 16kg in front of the furnace, soybean oil 17kg, limestone 5kg, aluminum oxide 10kg, dolomite 11kg, bentonite 17kg, iron red epoxy ester primer 7kg, zirconia 4kg, water 1000kg. It is worth noting that the gas dust removal system of the ironmaking blast furnace is composed of gravity dust removal and fine dust removal. The dry coarse dust collected by the first stage is called gravity ash; the second fine dust collector generally adopts dry type Bag filter or wet dust removal system, in which the dry fine dust obtained by dry dust removal is called gas ash; the sludge obtained by wet dust removal after precipitation treatment is called gas mud. The blast furnace used in the present invention Gas mud is the sludge obtained after the product o...

Abstract

The invention discloses a mold release agent for a pig-casting machine, which belongs to the technical field of mold release agents for metallurgy and foundry. The mold release agent provided by the invention comprises, by mass, 20 to 25 parts of blast furnace sludge, 10 to 13 parts of ash collected from the head of a sintering machine through electric precipitation, 16 to 23 parts of fly ash collected from an ore groove at the front of a furnace, 15 to 17 parts of soybean oil, 5 to 7 parts of limestone, 9 to 10 parts of alumina, 11 to 15 parts of dolomite, 17 to 19 parts of bentonite, 7 to 8 parts of an iron red epoxy ester primer, 3 to 5 parts of zirconia and 800 to 1000 parts of water. According to the invention, the blast furnace sludge, the ash collected from the head of the sintering machine through electric precipitation and the fly ash collected from the ore groove at the front of the furnace which are wastes difficult for comprehensive utilization in a steelworks are used as a part of the components of the mold release agent, so the wastes are recycled and production cost of the steelworks is greatly reduced; moreover, the mold release agent can effectively adhere on the inner surface of a mold and forms an effective separating layer between molten iron and a pig mold, demolding can be realized without extra knocking of the cast iron machine, and a cast iron ingot has a smooth surface.

Description

technical field [0001] The invention relates to the technical field of mold release agents for metallurgical casting, and more specifically, to a mold release agent 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 furnace to t...
