1. The cooling water pipe adopts the super-long seamless steel pipe, theinner part of the wall body is not provided with a joint, the water pipe threadhead is directly formed, and the special water pipe positioning process ensuresthat the water pipe is not damaged;
2. The water pipe bending system adopts the special mould, the ellipse issmaller, and the ball passing rate is higher.
3According to the requirements of users,a variety of anti-Carburizing processes can be used to treat the surface ofcooling water pipes to meet the needs of all kinds of users.
4The shape and size of the cooling staveis accurate to ensure the smooth installation of the cooling stave.
5The resin sand molding is adopted, thesurface of the cooling stave is smooth and clean, the size is accurate, and theinternal quality is reliable.
6There is no oxidation phenomenon in theinner wall of the water pipe, and the thermal conductivity of the cooling wallis good.
7The cooling wall material can meet orexceed the national standard requirements stably.
8Ã£â¬Can carry on all kinds of related testsrelated to the cooling stave, and issue the test report.
Type of production
The heat surface of the cooling wall is a dovetail groove which isarranged at intervals, and the refractory material is tamped in the groove. Hasthe characteristics of convenient construction, good thermal conductivity andconvenient slag hanging. It is mainly used in the middle and lower parts of thefurnace, the waist and the furnace body. The material of the cooling wall is:qt450-10, qt400-18, qt400-20, etc., and the refractory materials such ascarbonaceous, aluminum-carbon, or silicon carbide are tamped in the tank.
4Fully covered brick cooling stave(Coldor hot inlay)
The cooling stave is characterized by the unity of brick wall, thehot surface (working face) is all covered by refractory brick, and the innerside adopts thin lining structure or no lining structure, which can expand thefurnace capacity. Mainly used in furnace belly, furnace waist and lower part offurnace body. The cooling wall material is qt450-10,qt400-18,qt400-20 and soon, and the brick material is phosphate impregnated clay brick, firedmicroporous aluminum-carbon brick, silicon carbide brick and so on.
5Inverted c cooling stave
The cooling wall is a c-shaped structure, and is arranged on thebody part of the blast furnace body and is combined with the furnace throatsteel brick to play a good role in resisting the impact and the abrasion of theburden. Is generally used for large and medium-sized blast furnaces. Thematerial of the cooling wall is: QT400-18, QT400-20, etc.
