Wanding contains other products and information you need, so please check it out.

The quality of calcium carbide is the most important factor when selecting a supplier. It directly impacts production efficiency and product quality, especially in metallurgy and acetylene production. A reliable supplier should have a rigorous quality control system to provide stable and standardized products.

Key indicators for evaluating reliability include whether the supplier is ISO certified and whether they can provide inspection reports for each batch of products. TYWH (Tianjin Tianyuan Weihong Import & Export Co., Ltd.) is ISO certified, and every batch of calcium carbide products comes with a detailed inspection report to ensure that key quality metrics such as gas generation and impurity content meet international standards.

1.2 Production Capacity

A supplier’s production capacity determines whether they can supply products consistently and reliably over the long term. Companies should choose suppliers with high production capacity and flexible scheduling capabilities to handle fluctuating market demands. Efficient production capacity ensures timely delivery and reduces supply chain risks caused by production delays.

2.1 On-Time Delivery

The delivery time of calcium carbide directly affects the production schedule. For businesses, ensuring that the supplier delivers on time and avoids production interruptions is a crucial factor when selecting a supplier. A reliable supplier should have a well-established production and logistics management system to ensure timely deliveries.

2.2 Supply Chain Transparency

Supply chain transparency is a key factor in ensuring on-time delivery. Companies should choose suppliers that provide complete supply chain management information, allowing them to track the production and transportation progress of their products, reducing the risk of delays due to unforeseen circumstances.

3.1 Transparent Pricing Strategy

The price of calcium carbide directly affects a company’s production costs. When selecting a supplier, it is essential to focus on price transparency, ensuring that the quoted prices are reasonable and free from hidden costs. Very low-priced calcium carbide products may imply compromised quality. Companies should strike a balance between price and quality when making a selection.

Calcium carbide, with the chemical formula CaC₂, is a crucial compound in various industrial applications, including the production of acetylene gas, desulfurization in steel manufacturing, and as a ripening agent. The production of calcium carbide involves a complex process that requires high temperatures and specific raw materials. In this article, we will delve into the details of calcium carbide production in a plant setting, highlighting the key steps, equipment, and applications.

Introduction to Calcium Carbide

Calcium carbide is an inorganic compound that appears as a white powder or colorless crystals in its pure form. However, industrial-grade calcium carbide often presents as a gray-black or brownish solid due to impurities. It is highly reactive, especially with water, producing acetylene gas and calcium hydroxide, which makes it a vital material in industries such as welding, steel production, and chemical synthesis.

Chemical Properties and Applications

Calcium carbide has a molecular weight of 64.099 g/mol and a density of 2.22 g/cm³. Its melting point is approximately °C, and it boils at about °C. The compound is widely used for producing acetylene, which is essential in welding and cutting processes. Additionally, calcium carbide serves as a desulfurizer in the steel industry, improving steel quality by removing sulfur impurities.

Calcium Carbide Production Process

The production of calcium carbide involves several key steps:

1. Raw Material Preparation: The primary raw materials are calcium oxide (lime) and carbon, typically in the form of coke or anthracite. These materials must be crushed and mixed in a specific ratio, usually 1 part lime to 3 parts carbon.

2. Heating in an Electric Arc Furnace: The mixture is then heated in an electric arc furnace at temperatures ranging from °C to °C. This high temperature is necessary to initiate the reaction between calcium oxide and carbon.

3. Reaction: The reaction between CaO and C produces calcium carbide (CaC₂) and carbon monoxide (CO). The chemical equation for this process is:

CaO+3C→CaC2+CO

This reaction is endothermic, requiring significant energy input to drive off the carbon monoxide.

4. Cooling and Solidification: After the reaction is complete, the furnace is cooled, allowing the calcium carbide to solidify.

5. Crushing and Packaging: The solid calcium carbide is then crushed into smaller pieces and packaged for distribution.

Equipment Used in Calcium Carbide Production

- Electric Arc Furnace: This is the primary equipment used for calcium carbide production. It provides the high temperatures necessary for the reaction between lime and carbon.

- Soderberg Electrodes: These are used in closed furnaces to improve efficiency and reduce energy consumption.

- Coke Dryer: Used to remove moisture from coke before it is mixed with lime.

- Lime Kiln: Converts limestone into lime by calcination.
