Silicon Aluminum Calcium Alloy

Introduction

Silicon Aluminum Calcium Alloy has strong affinity with oxygen, sulfur, hydrogen, nitrogen and carbon in molten steel, so it is usually used as Oxygen scavenger and desulfurizer. In addition, adding this product to the molten steel can generate a strong exothermic effect, which is beneficial for maintaining the temperature of the molten steel. Calcium vapor also has a stirring effect on molten steel, which is conducive to the floating of non-metallic slag. In the production of cast iron, silicon calcium alloy is more effective in improving the properties of cast iron than silicon iron. This product is not only an effective inoculant for promoting the formation of nodular graphite, but also has the functions of deoxidation, desulfurization, denitrification, and silicon enhancement. We have been engaged in this industry for many years, with rich experience and mature technology, so you can always consult us if you have any questions.

This product is often used as Oxygen scavenger and desulfurizer in steelmaking. Calcium and sulfur will form a stable compound CaS that is insoluble in molten steel. In addition to magnesium and rare earth metals, calcium can also reduce the oxygen and sulfur that hinder the formation of spherical graphite. This product can effectively avoid the problems of nodulation and blockage at the ladle nozzle. Treating molten metal with this product can improve the physical and chemical properties of the metal, as well as facilitate the purification of inclusions such as oxides and sulfides. This product not only has strong deoxygenation ability. And it also improves the performance of the steel. Improved the plasticity, impact toughness, and flowability of steel.

Features

1. Silicon Aluminum Calcium Alloy has a variety of deoxygenation components, with the characteristics of low melting point and fast diffusion, which can fully deoxygenate and promote desulfurization.

2. The calcium based elements in this product can effectively spheroidize inclusions in molten steel, change the shape of the inclusions, and thus purify the molten steel.

3. This product is widely used in processes such as rapid tapping in front of the furnace and refining outside the furnace. It can improve smelting speed, shorten smelting time, and play a significant role in reducing steelmaking costs.

4. This product is smoke-free, dust-free, odorless, and fluorine-free, and will not cause harm to the health of operators.

5. This product has the advantages of non hygroscopic, non crushing, good stability, and easy storage.

Application

-Hardener: used to enhance the physical and mechanical properties of metal alloys.

-Grain Refiner: Used to control the dispersion of individual crystals in metals to produce finer and more uniform grain structures.

-Modifiers and special alloys: commonly used to improve strength, ductility, and workability.

Advantage

Silicon Aluminum Calcium Alloy is used as a powerful Oxygen scavenger and desulfurizer in the production of high-grade steel, low-carbon steel and stainless steel. In fact, both calcium and silicon have a strong chemical affinity for oxygen. Especially calcium has a strong chemical affinity not only for oxygen, but also for sulfur and nitrogen. Calcium silicon is used to control the shape, size, and distribution of oxide and sulfide inclusions, thereby improving the flowability, processability, ductility, and impact performance of steel products.

Purpose

(1) This product is an auxiliary material for steelmaking. Suitable for deoxidation in various forms of steelmaking, especially suitable for converter steelmaking.

(2) The product is a composite Oxygen scavenger product, in which silicon and oxygen have good affinity. It reacts to generate silicon dioxide impurities, which float on the surface of the molten steel and are easy to remove.

(3) The deoxygenation effect of this product reduces inclusions.
