Embodiment Construction

[0018] The technical solutions of the present invention will be described in detail below with reference to preferred embodiments.

[0019] In order to reduce the production cost of the product, the invention utilizes low-carbon steel raw materials, adopts an annealing process and innovates the electroless plating process to produce high-hardness galvanized sheets that meet customer requirements.

[0020] The invention adopts low-carbon steel grades, and can produce high-hardness galvanized steel sheets by controlling parameters such as annealing temperature, heating time, cooling speed, and cooling temperature. At the same time, it accumulates and summarizes various process parameters, judges the actual performance status of the current galvanized sheet through simple parameter comparison, and adjusts the current strip steel in real time, eliminating the lag of product performance adjustment.

[0021] Step 1: Uncoiling, welding, filling and discharging of imported low-carbon ...

Abstract

The invention discloses a method for producing high-hardness galvanized plates by using low-carbon steels as raw materials. The method comprises the following steps: carrying out annealing treatment on strip steels; and carrying out chemical galvanization on the strip steels. By the method, cost of raw materials is greatly reduced, the produced high-hardness galvanized plates are good in performance index, adhesion of zinc layers is high, and the hardness value is completely greater than 75 HRB.

Description

technical field [0001] The invention relates to a material processing technology, in particular to a production method for producing high-hardness galvanized sheets using low-carbon steel raw materials. Background technique [0002] The hardness of galvanized sheets produced by conventional galvanizing lines is generally low, but there is a demand for high-hardness galvanized sheets in the market. Customers require the hardness of galvanized sheets to be above 75 HRB, but the hardness of galvanized sheets produced by low-carbon steel is only 50HRB-60HRB. In order to produce high-hardness galvanized sheets, the usual method is to increase the alloy content and carbon content of the raw steel sheets, that is, to use high-alloy raw materials, increase the carbon content, and add Si, Mn and rare earth elements. But doing so will increase the cost of raw materials, making the cost of the whole process increase. Contents of the invention [0003] The technical problem solved b...
