What are the characteristics of the production process of container angle parts?

Container corner is an important force component on the container, often subject to stacking, buckle and lifting, complex shape, general casting forming, in order to ensure performance requirements, must be heat treatment. The traditional heat treatment is using the process (930 degrees C x 3h, water quenching , 680 degrees C, tempering).

What are the characteristics of the production process of container angle parts

Theoretically, it is difficult to form even tissue for low-carbon, low-quenchable container angle castings, and the traditional heat treatment process requires two heating treatments, which are large in power consumption, thick oxide skin, large processing volume and high production costs. Reducing the traditional process of container angle castings to a single-fire treatment, if it can meet the requirements of mechanical properties, will greatly reduce production costs and create great economic benefits. This topic uses a positive fire instead of the quality treatment, the blanks are first heat treatment, and then processed into a standard sample.

Strength and plasticity test was carried out by stretching machine, and toughness test was carried out by the impact machine, the specimen phase tissue and cut-off profile under two process conditions were observed by using a gold phase microscope and a scanning electron mirror, and the hardness of the specimen was tested with a hardness gauge. The test results show that a positive fire, 910 degrees C, the yield strength of the sample under the s300 MPa, tensile strength of b 500 MPa, the elongation rate after the break of the elongation of 30%, the after-break shrinkage rate of 60%, -40 degrees C low temperature impact function Ak 60J, fully able to meet the mechanical performance requirements of the various stage societies diagonal parts.
