The material of Cast Iron Measuring Plate is high-strength cast iron HT200 and HT250. After two times’ artificial heat aging treatment( Artificial annealing temperature 600℃ to 700℃or 2-3 years natural aging) the internal stress was totally eliminated, so the surface plate have stable accuracy and good wear-resisting performance.
測量平臺的包裝：鑄鐵測量平臺采用鐵板包裝或木制包裝兩種形式，鑄鐵測量平臺表面用塑料膜封裝，這種包裝適于鑄鐵測量平臺內(nèi)陸運輸，并有良好的防潮、防震、防銹和防野蠻裝卸等，保護鑄鐵測量平臺的措施,以確保安全運抵現(xiàn)場。
測量平臺在使用時，要先進行安裝調(diào)試，始終保持工作面的清潔，使用過程中，要注意被測工件和測量平臺的工作面不能有強烈的碰撞，工件的重量更不可以超過測量平臺的額定載荷，如超過就有可能損壞測量平臺的工作面，甚至會造成變形，使之損壞，無法使用。
Package:
The Cast Iron Measuring Surface Plate shall be packed by iron plate or wooden cases and working surface shall be covered with plastic film, which can protect the surface plate against moisture, shock, rust and rough handling, to ensure the surface plate be delivered to the destination safely.
Before using, the Measuring Surface Plate shall be mounted and debugged. When used, the working surface should be kept clean and be protected from damage. To ensure there is no collision between the workpiece and working surface and the weight of the workpiece should not exceed the loading capacity of the surface plate or it may cause damage to the working surface and it even can cause deformation.
