In order to prevent deformation of the cast iron T slots plate, when using a crane to lift it, four round steels of the same length should be inserted into the lifting hole, and then the same length of oil wire rope should be used for lifting, and the cast iron T slots plate should be transported in a balanced tools.

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.
