鑄鐵平臺修理室的溫度很重要，太低或太高都不容易嵌砂，一般溫度在20度，一般研磨鑄鐵平臺在壓砂前等溫數小時(shí)或更長(cháng)時(shí)間，待鑄鐵平臺變形穩定后，再開(kāi)始研磨。有的單位壓砂房間恒溫條件比較差，當鑄鐵平臺從一溫度拿到另一溫度的房間研磨時(shí)，平板受熱漲冷縮現象的影響，表面產(chǎn)生變形，故等溫一段時(shí)間。
對于鑄鐵平臺和表面劃痕、碰傷較重的鑄鐵平板，先用油石打磨一下，打磨后，我們先用M4的砂子修一下板面，三塊研磨平臺互相研磨，待推拉費力的時(shí)候，卸下鑄鐵平臺，直到鑄鐵平臺板的平面度較好時(shí)，停止修理平板，做到心里有數。對于使用中劃痕、碰傷較輕的鑄鐵平臺，只用油石把突起的部分打磨下去就行，不用修理鑄鐵平臺，直接壓砂就可以了。
鑄鐵平臺灣同胞在制造過(guò)程中進(jìn)行取樣理化試驗、金相分析，考核產(chǎn)品是否達到各項技術(shù)指標。劃線(xiàn)平臺工作面的硬度應為HB170-220,劃線(xiàn)平臺工作面應采用刮削工藝。劃線(xiàn)平臺用完后擦凈，涂無(wú)水酸性的防銹油，覆蓋防潮紙，置于清潔干燥處存放。劃線(xiàn)平臺使用前用無(wú)腐蝕性汽油，將工作面的防銹油洗凈，并用脫脂棉紗擦拭干凈，方可使用。溫度變化會(huì )使測量產(chǎn)生誤差，應在20±50C范圍內使用。劃線(xiàn)平臺用時(shí)小心、嚴防碰撞。劃線(xiàn)平臺使用時(shí)用水平儀調整到水平，使支點(diǎn)均勻分布各支點(diǎn)上。
The temperature of the repair room of the cast iron platform is very important. It is not easy to embed sand if it is too low or too high. Generally, the temperature is 20 degrees. Generally, the grinding of the cast iron platform is isothermal for several hours or longer before sand pressing. After the deformation of the cast iron platform is stable, the grinding can be started. The constant temperature condition of some unit sand pressing room is relatively poor. When the cast iron platform is grinded from one temperature to another, the surface of the plate will be deformed due to the effect of the expansion and contraction of the plate when heated, so it will be isothermal for a period of time.
For the cast iron platform and the cast iron plate with heavy scratches and bruises on the surface, first polish them with oilstone. After polishing, we first polish the plate surface with M4 sand. The three grinding platforms grind each other. When it is hard to push and pull, dismantle the cast iron platform. When the flatness of the cast iron platform plate is good, stop repairing the plate, and have a good idea. For the cast iron platform with slight scratches and bruises in use, it is only necessary to polish the protruding parts with oilstone. Instead of repairing the cast iron platform, it is OK to press sand directly.
During the manufacturing process, the Taiwan compatriots of cast iron shall carry out sampling physical and chemical test and metallographic analysis to check whether the products meet the technical indexes. The hardness of the working surface of the scoring platform shall be hb170-220, and the scraping process shall be adopted for the working surface of the scoring platform. Clean the marking platform after use, apply the anti rust oil without water and acid, cover with moisture-proof paper, and store it in a clean and dry place. Before use, the marking platform shall be cleaned with non corrosive gasoline, antirust oil on the working surface, and wiped clean with absorbent cotton yarn before use. Temperature change will cause measurement error, and it should be used within 20 ± 50c. When using the marking platform, be careful and prevent collision. When the marking platform is used, adjust it to the level with a level meter to make the fulcrum evenly distributed on each fulcrum.
