In the first ten days of February 2020, the key statistics show that steel enterprises produce a total of 19.3943 million tons of crude steel, 17.9747 million tons of pig iron, 17.5904 million tons of steel and 3.225 million tons of coke. This ten day average daily output of astm a242 type 1 steel properties crude steel is 1939400 tons, down 2.68% on a month on month basis, up 3.16% on a year-on-year basis; steel is 1759000 tons, down 9.09% on a month on month basis, up 2.51% on a year-on-year basis.
The melting points of vanadium and chromium are relatively high, and the ability to interact with oxygen is also relatively large, so the metal melt should be deoxidized well, and the temperature of the wear plate melt should not be too low, exceeding 1550℃. Boron is an element that is relatively easy to be oxidized and nitridated, so the steel melt must be fully deoxidized and nitrogen fixed before adding. In general wear-resistant plates, astm a242 type 1 steel properties, boron is added as a trace element, and the amount used is not very large.
