Abstract

The invention discloses a cooling stave and a machining method thereof, and belongs to the field of cooling staves. The machining method includes the following steps of 1, production of a wood pattern of the cooling stave; 2, production of a sand mould and distribution of a cooling water pipe, specifically, putting the wood pattern of the cooling stave into a sand box, compacting the pattern of the sand mould, taking the wood pattern of the cooling stave out to form a cavity, and distributing the cooling water pipe in the cavity; the cooling water pipe comprises a first cooling water pipe, a second cooling water pipe and a third cooling water pipe; 3, injecting liquid steel into the cavity and starting casting; and 4, conducting cooling and forming after casting. According to the cooling stave and the machining method thereof, the defect that a cooling stave is prone to happening melt-through of cooling water pipes is overcome, by laying multiple layers of cooling water pipes in the cooling stave, the cooling effect is improved, and by strictly controlling the machining process, melt-through of the cooling water pipes can be effectively prevented so as to achieve the technical effects of fused while not molten and seamless fusion.

Description

technical field

[0001] The invention relates to the technical field of staves, and more specifically, relates to a stave and a processing method thereof. Background technique

[0002] A large number of staves are used in iron-making blast furnaces. Compared with the currently widely used ductile iron staves, cast steel staves as a new generation of blast furnace staves have high elongation, high tensile strength, high melting point, and thermal shock resistance. Good performance and good overall thermal conductivity. The material of the cast iron stave base and the cooling water pipe is very different. Due to the limitation of the base material and casting process, there is an air gap of 0.1-0.3 mm between the base and the cooling water pipe, resulting in an increase in thermal resistance. However, the cast steel stave matrix and the cooling water pipe are made of the same or similar material. The special casting technology makes the outer wall of the cooling water pipe and...
