An environmentally friendly water-based coating that reduces scale formation by 40%-90% during steel ingot heating, prevents decarburization by 70-100%, and peels off automatically during cooling after furnace discharge. Applied to metal surfaces at room temperature, it forms a dense coating after sintering at high temperatures.

While ensuring the mechanical properties of the steel ingot after hot processing such as forging, rolling, and heat treatment, it also improves surface quality, reduces cold processing allowance, enhances production efficiency, and offers significant economic benefits.

This product effectively addresses the following issues that occur after billets and steel materials enter the heating furnace:

1) Oxidation loss—Secondary oxidation   Oxidation loss rate approx. 0.8~5%;

2) Surface depletion of alloy elements and decarburization—  Surface segregation, copper embrittlement;

3) Poor descaling performance and low product qualification rate—Oxide embedding    Landscape patterns, mountain peak patterns;

4) Surface quality issues and defects—Oxidation spots, residual oxidation, red rust; Edge cracks, microcracks; Roller marks;

5) Increased energy consumption and pickling processes;

6) Scale erosion of the furnace body, affecting furnace lifespan.

I. Product Overview

An environmentally friendly aqueous slurry composed of minerals, metallurgical ore powder, inorganic industrial powders, and high-temperature composite binders. Applied to metal surfaces before hot processing such as forging, rolling, and heat treatment, it forms a dense coating after sintering at high temperatures. No harmful gases are released during the process, and it does not affect the surface composition of the steel ingot. The coating is self-peeling, reducing scale and decarburization layer formation during hot processing, lowering cold processing allowance, improving yield, and ensuring good surface quality. Mainly suitable for alloy structural steel, mold steel, high-temperature alloys, titanium alloys, and other materials.

III. Storage and Packaging

1. The product is stored separately as powder and liquid, with a shelf life of 12 months for the powder and 3 months for the liquid.

2. Prepared slurry should be stored sealed in a cool place after use, with a shelf life of 7 days. It must be stirred evenly before use.

3. Store in a dry, ventilated, and cool place. Packaging containers must remain sealed.

4. Packaging: Powder and liquid are packaged separately, used as a two-component system (slurry ratio by weight: powder to liquid 1:0.6-0.7). Liquid is packaged in plastic buckets, powder in plastic buckets or waterproof paper bags. Specifications after mixing: 20/30/50kg or as per customer requirements.
