The hardness of the cast iron floor plate is lower than 45HRC in the state of quenching and tempering, annealing, and normalizing of the workpiece.

In order to solve the problem of cracks of sintering trolley fence caused by heat, deformation due to large temperature gap between the upper and lower sides of sintering trolley fence, high replacement cost, the following improvement measures are proposed.

As one of the main components of the sintering trolley, the fence of the trolley is also a vulnerable part.

The blisters on the cast iron base plate are a common defect in the production of castings. The reason is that the gas in the molten metal is not discharged before the solidification of the casting.

Cast iron surface plates are indispensable workbenches for marking, measuring, riveting, welding, inspection, and tooling processes. Among them, heavy industry is the most commonly used, accounting for the total 95% of production.

Cast iron work table is also called cast iron plate, cast iron T slotted plate, cast iron bed plate, cast iron floor plate etc. which is a widely used measuring tool in CNC machine.
