Manganese Silicide Ferroalloy Dephosphorizing Principle And Technology Research Outside Of The Furnace

Steel production of phosphorus can cause brittle cold products, seriously affecting the performance of the steel. Typical modern clean steel content of phosphorus require control to 3ppm or less, require high quality steel in the phosphorus content is less than 0.005%. Because of these high quality steel production, use low-phosphorus alloy materials, and reduce phosphorus alloy impurities due to limited resources, cost, technology, equipment and other factors over the years have not been solved. Therefore, the development of production and to market to provide cost-effective, low-phosphorus-containing alloy products, providing quality alloy material for the production of high quality clean steel alloy has been an important topic in the field of scientific and technical personnel.This article describes the process used to restore the dephosphorization ferroalloy production technology to solve the core powder recipe selection applies to low-carbon and low carbon silicon manganese alloy manganese silicon alloy and anti rephosphorization dephosphorization fluxes selection and dephosphorization slag harmless Problem treatment method of choice for the production of low-cost carbon phosphorus silicon manganese alloys and micro-carbon manganese silicon alloy opened up a new path.The main research topics are as follows:... A study of silicon manganese ferroalloy smelting process, the two outer silicon manganese ferroalloy furnace dephosphorization process design, silicon manganese alloy Dephosphorization 3 Effect of four silicon manganese ferroalloy dephosphorization effect and factors the studyFollowing results were obtained by analyzing the experimental study:cored wire method using silicon manganese ferroalloy furnace dephosphorization were significantly reduced after dephosphorization P content alloy, alloy after dephosphorization P content in an average reduction of 37%, the maximum reduced 46.8%. After dephosphorization alloy content of each element can meet the national standard, and Jilin Ferroalloy Plant standards. Tons of iron consumption volume and dephosphorization front line have some influence on the alloy composition dephosphorization effect, where tons of iron consumption of the thread, before dephosphorization P alloy of manganese, phosphorus content greater than other factors.The innovation of this study is to develop cored wire through the core powder and anti rephosphorization flux formula, solve ways to improve the conditions of the reaction kinetics, anti rephosphorization fluxes choose to apply, harmless ways dephosphorization slag and other key technologies. Compared with the prior art, the proposed specific core powder formulations to prevent rephosphorization resulfurization slag formulations and dosage, is the use of specific desulfurization dephosphorization suitable liquid carbon silicon manganese alloy or low carbon silicon manganese alloy in the furnace, so may be apparent in the course of reaction feed line by adjusting the feed line speed to control the reaction time, the amount of feed lines and other parameters, in order to achieve maximum cost dephosphorization, desulfurization rate. Since this study is the furnace processing, process methods and equipment simple, safe and reliable, dephosphorization, desulfurization rate stability, the present invention has the energy efficient, safe, reliable, low cost, etc., is the production of phosphorus sulfur carbon silicon manganese alloys, low ideal way to micro phosphorus sulfur carbon silicon manganese alloy products.
