Novel slope-forming brick for wall of ladle and slope forming process

Abstract

The invention relates to a novel slope-forming brick for a wall of a ladle, which is characterized in that an included angle between a thick-end side surface and a bottom surface of the slope-forming brick is less than 90 degrees, and an included angle between a thin-end side surface and a bottom surface of the slope-forming brick is more than 90 degrees. The invention further relates to a novel slope-forming process for the wall of the ladle by using the slope-forming brick mentioned above, which is characterized in that: a masonry structural unit comprises a first slope-forming brick Q1 (8), a first slope-forming brick Q2 (9), a first slope-forming bricks Q (10), a second slope-forming brick Q1 (8), a first sheet-like brick arranged on the second slope-forming brick Q1 (8), a second slope-forming brick Q2 (9), a second sheet-like brick arranged on the second slope-forming brick Q2 (9), a second slope-forming bricks Q (10) and a third sheet-like brick arranged on the second slope-forming bricks Q (10); the masonry structural unit is constructed circularly until reaching the masonry end, resulting in a slope structure with repeated initial end. The process ensures the uniformity of slope of the spiral upward masonry, so as to completely eliminate the over-standard horizontal brick joints and the over-standard triangular vertical brick joints and thus to ensure the masonry quality. The novel slope-forming brick for the ladle and the slope structure can completely eliminate the accident potential of steel seepage and steel leakage and effectively prolong the service life of the masonry structure.

Description

technical field [0001] The invention relates to a molten steel tank, in particular to a slope-raising brick for a tank wall of a molten steel tank and a slope-raising process. Background technique [0002] Steel ladle (also known as ladle, commonly known as large tank, such as Picture 1-1 , shown in 1-2) is a container for carrying molten steel in the steelmaking process. So far, the working layer of the molten steel tank wall built with universal arc bricks has been built with double-headed masonry and double-helix masonry at the two trunnions respectively, such as figure 2 As shown, due to the existence of inflection points before and after the double helix slope, in the process of upward spiral masonry, there will inevitably be excessive horizontal brick joints and excessive triangular vertical joints at the inflection points. Exceeding the standard horizontal brick joints and exceeding the standard triangular vertical joints are major hidden dangers that lead to ste...
