Production method of sintering machine trolley heat insulation pad

The invention relates to a production method of a sintering machine trolley heat insulation pad, which comprises the following steps: 1) the sintering machine trolley heat insulation pad is modified, the modified sintering machine trolley heat insulation pad comprises a groove-shaped body, the opening of the groove-shaped body is downward, the notch is matched with a support beam, the upper bottom surface of the notch is provided with a bulge extending along the length direction of the heat insulation pad, and the cross section of the bulge is arc-shaped; comprising a first transition arc, a protruding arc and a second transition arc which are sequentially connected, the outer side of the first transition arc is in smooth transition with the upper bottom face of the notch, and the outer side of the second transition arc is in smooth transition with the upper bottom face of the notch. (2) horizontal continuous casting is conducted, specifically, the sintering machine trolley heat insulation pad is subjected to
