Maintenance steps for cast iron plate

generally, the maintenance of cast iron plate includes the following steps: 1 pad and level the support points of cast iron plate to ensure that each support point is stressed evenly and the whole cast iron plate is stable. 2. In order to prevent the deformation of the cast iron plate, when hoisting the cast iron plate, four steel wire ropes of the same length shall be used to hang the four lifting holes on the cast iron plate at the same time, and the cast iron plate shall be hoisted stably on the transportation tool. 3. When using the cast iron plate, the workpiece shall be handled with care, and the rough workpiece shall not be moved on the cast iron plate, so as to avoid bumping, scratching and other damage to the working surface of the cast iron plate. 4. During the installation of the cast iron plate, each support point of the cast iron plate is padded and compacted with adjusting sizing blocks. A professional technician fixes a lead screw (25) to the cast iron plate adjusting worm gear (29), and a pair of radial thrust roller bearings (27) moves the lower nut force application plate up and down (with two fixed columns as guides) to tighten the force application spring (24). Through the upper force application plate and the load sensor (19), the experimental force is applied to different friction pairs to generate contact pressure, The test shall be carried out as required to achieve acceptable accuracy. 5. In order to prevent the overall deformation of the cast iron plate, the workpiece shall be removed from the cast iron plate after use to avoid the deformation of the cast iron plate without warping caused by the heavy pressure of the workpiece on the cast iron plate for a long time. 6. Cast iron plates shall be subject to periodic weekly inspection according to national standards, and the inspection cycle can be months according to specific conditions. 7. Cast iron flat plate shall be 1) all items except 5.8 and 5.12 shall be installed in a ventilated and dry environment and away from heat source, corrosive gas and corrosive liquid. 8. When the cast iron plate is not in use, the working surface shall be cleaned in time, and then coated with a layer of anti rust oil, which shall be covered with anti rust paper. The cast iron plate shall be covered with the outer package of the cast iron plate to prevent damage to the cast iron plate working surface
