SPCC steel drum performance optimization heat treatment method

Abstract

The invention discloses an SPCC steel drum performance optimization heat treatment method. The method comprises the following steps that firstly, a steel drum is cleaned and subjected to leakage inspection before heat treatment of the SPCC steel drum; secondly, the temperature of a salt bath furnace is set to be 200 DEG C-250 DEG C, the SPCC steel drum is hoisted to a position above the salt bathfurnace after the temperature reaches 200 DEG C-250 DEG C, a bottom cover of the SPCC steel drum is kept horizontal while being immersed into the salt bath furnace, the immersion depth is 38-42 mm, the SPCC steel drum is subjected to heat preservation in the salt bath furnace for 10 min-15 min under the condition that the immersion depth is 38-42 mm and the temperature is 200 DEG C-250 DEG C, andthen the SPCC steel drum is taken out of the furnace and air-cooled to the room temperature; and thirdly, salt on the surface of the SPCC steel drum which is heated and cooled in the second step is cleaned. According to the SPCC steel drum performance optimization heat treatment method, the performance of a new drum which is not used yet can be improved, and the risk of fracturing is lowered; andthe steel drum after transportation can also be saved from fatigue impact, the service life is prolonged, accordingly, reuse is achieved, and the characteristics of the mechanical performance, the fatigue resistance and the like of the whole steel drum are improved.

Description

technical field [0001] The invention belongs to the field of heat treatment technology, and in particular relates to a performance-optimized heat treatment method for an SPCC steel drum. Background technique [0002] Packaging steel drums are a widely used container. With my country's accession to WTO and the expansion of international trade, the scope of use of steel drums has become increasingly widespread, and great changes have taken place in transportation methods and transportation distances. Liquid dangerous chemicals are the most sensitive dangerous goods, and closed steel drums are one of the main transport packaging containers for exporting liquid dangerous chemicals. More than 90% of steel drums on the market are made of SPCC materials. Due to work hardening and edge effects, the curling of steel drums has become a stress concentration point and a weak point in mechanical properties, so most of the leakage points of leaked steel drums are concentrated in the cur...
