Embodiment Construction

[0009] Below in conjunction with embodiment, further set forth the present invention. In the following detailed description, certain exemplary embodiments of the invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments can be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the description is illustrative in nature and not intended to limit the scope of the claims.

[0010] A short-flow casting modifier, including the following components, Sn, Bi and Sb; the weight ratio of the above components to the weight percentage of casting molten iron in the furnace body is: Sn 0.01%-0.1%, Bi 0.02%-0.1% , Sb 0.1% ~ 0.4%.

[0011] The weight percentages of Cr, Mn and Mo in this embodiment are: Cr 0.05%, Mn 0.06%, Mo 0.3%, the Sn is pure tin, and the effect is best when the particle size is 0.1-3mm, and the The furnace body is an i...

Abstract

The invention discloses a short-process casting modificator. The short-process casting modificator comprises the following components in percentage by weight based on casting molten iron in a furnace body: 0.01%-0.1% of Sn, 0.02%-0.1% of Bi and 0.1%-0.4% of Sb. Blast-furnace molten iron is directly accessed into a medium-frequency furnace for being modulated, elements such as Sn, Bi and Sb which hinder graphitization are added into the medium-frequency furnace to improve binding force among Fe and C atoms, so that growth of thick and straight graphite is hindered; stokehole primary inoculation treatment is strictly controlled, and an efficient inoculant is adopted for secondary inoculation technology with casting molten iron flow, so that a hereditary problem of the blast-furnace molten iron is solved better, and phenomena that much electric energy and shaping materials such as cokes and lime stones are wasted are avoided; meanwhile, the problems that a large number of solids and gas wastes are discharged in melting, pollution is heavy, energy consumption is high and benefits are low are solved.

Description

technical field [0001] The invention relates to a modifier, in particular to a modifier specially used for short-flow casting of gray cast iron brake discs. Background technique [0002] When molten iron in a blast furnace is solidified into pig iron ingots, graphite will aggregate into coarse graphite. When the pig iron ingot is remelted, the compounds formed by these coarse graphites can be used as new crystallization cores. However, in short-process smelting, the carbides precipitated from blast furnace molten iron are far smaller than those precipitated from pig iron ingot melting, with fewer crystallization cores and large heredity of molten iron. Therefore, it is necessary to add a modifier to reduce the genetics of blast furnace molten iron. Sex, the effect of improving the quality of molten iron. However, the modificator in the prior art has many types of component content, which is inconvenient to prepare, and is likely to have unpredictable effects on casting prod...
