Description of the Invention: [Technical Field of the Invention] The present invention relates to a refractory-washing material, and more particularly to a slag-casting material for a main furnace of a blast furnace which is repaired by an injection molding method. . / [Prior Art] - In general, the New Zealand molding method is used to repair the main stream of ironmaking blast furnace. Most of them are calcium silicate cement (CAC) as a binder; and _ oxidized dance in calcium cement (Ca〇) and oxidized sand (Si()2) are easy to shape at high temperature. • $化铭-Oxygen (4)—Oxidized oxide ternary compound (1) must be-(10)-Si〇2) and become a low-refined phase in the material. In addition, when the cement (CAC) is used as the binder, the water is required to achieve the effect of hydration condensation and solidification, and the added water is in the flooding (4). The type exists, the higher the temperature and the longer (four) dry time: the 'will be removed' to avoid the problem of bursting of the material during the drying process or out of milling. < Because the defects of the sighting materials are mainly from the cement as the combination agent. Therefore, the development of the cementing material without cement binder is the solution to the current bottoming of the pouring materials. . SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a new blast furnace main flow _sol material which does not use cement as a binder.疋 矽 浇 主流 主流 主流 主流 主流 主流 主流 主流 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含Hardening with bismuth ingredients 201226573

The special/wang method of repairing the mainstream of the furnace is summarized as follows: 'The blast furnace mainstream road (4) Sol New Zealand material is proposed 201226573 - a new type, and the main (four) sol solution as a binder, to improve the existing alumina acid The casting material of calcium cement as a binder is used in the construction because the water exists in the form of crystal water, and it has to consume the disadvantages of higher temperature and longer drying time. At the same time, the present invention is used in the fourth time. After the application, it does not cause the problem of the decline of physical properties due to the fact that the casting material with calcium aluminate cement as a binder is used to form a compound of A12〇3 CaO S i 〇2 at high temperature. The performance of the product and the reduction of the flow path repair time have indeed achieved the creative purpose of the present invention.
