Increased welding t-slot table cast iron line Assembly aided cast iron bench Widely used in the construction industry, printing industry, hydraulic equipment, building construction, railway locomotives, equipment production, electronics, petrochemical, automotive, ceramic industry, railway locomotives, and other fields. In use should be avoided due to excessive wear, nicks and scratches, and the impact of plane precision and service life, under normal conditions, the life of cast iron test platform should be a long-term one. Should be cleaned after use, good rust prevention work, in order to maintain life.

1.1 environment temperature:-545

1.2 relative humidity: 95%

2, the main technical parameters and requirements of the platform:

2.1 cast iron grades of cast iron platform HT200

2.2 surface hardness HB=170-220

260N/tensile strength of 2.3 square meters

2.4 platform processing finish above 3.2

Flatness and straightness 2.5 work platform to meet clients or drawings

2.6 other unspecified technical requirements according to national standards for implementing

3.1 in the casting process, the strict control of casting the composition of five elements, requires no crack in the Workbench, ash. Surface defects according to national standards.

3.2 must guarantee twice-tempered during the casting process.

The first time: in tempering after casting inspection, eliminating casting when casting stress arising out of equilibrium.

Second: upon completion of the rough rough vibration aging and elimination of machining damage of casting stress arising out of equilibrium.

3.3 the geometric dimensions of the platform, product weight, size and shape and position tolerances, and other technical indicators produced strictly according to the drawings or technical requirements.

3.4 working platform surface rust brush, face brush primer twice, exposed surface then brush oil twice.
