用於改善燒結空氣滲透率的爐排棒具有棱鏡結構{.棱鏡的上部是梯形的，中間部分是矩形，下部是三角形{.矩形的長側，矩形的長邊與梯形的整個矩形相吻合，{{{1}棱鏡橫截面是等於矩形的長邊。 the trapezoidal surface of the grate bar is in contact with the material, and the triangular surface is in contact with the heat insulation sleeve. The lower part of the grate bar in contact with the heat insulation sleeve has a triangular structure, which reduces the contact area between the grate bar and the heat insulation sleeve, reduces heat conduction, and plays a role in protecting the設備.棱鏡橫截面的梯形的高度等於三角形的高度.它更有利於燒結材料層的空氣滲透性.
The height of the trapezoid of the prism cross section is equal to the height of the triangle. The length of the grate bar is 485mm. The upper bottom of the upper trapezoid is 26mm, the lower bottom is 30mm, and the height is 2mm. The rectangular size in the middle of the grate bar is 26mm×30mm;爐子的下部三角形的下部在爐排底部為30mm，高度為2mm .
爐排桿改善了燒結物材料層的空氣滲透性，改善了底部的空氣流量分佈，並減少了電隔離套在手推車底部的侵蝕，並且由於厚厚的燒結材料層的底部不僅改善了{0}}的損失，因此還可以減少con.的損失。
