Description

With a montly capacity of 100,000kgs and with more than 25 years of experience ensure the short delivery and the highest valued iron & steel casting parts.

Sand casting: Sand casting process is an industrial metal casting process that involves creating a mold from sand and pouring molten metal into it, generally used to cast the shaped parts of nearly any design, including large parts and those with internal passages. Baoding Guokun can produce various sand cast parts in cast iron, ductile iron, gray iron, low-carbon steel, mild steel, alloy steel for pump, valve, agriculture, railway, road, forklift, tillage, mining, automotive, medical, food, and aircraft, etc

The process of Baoding Guokun sand casting involves several steps after producing a professional tool or mold, including:

No.	Steps	Details
1	Pattern Creation	A two-piece metal pattern is created in the shape of the desired part, typically from iron, aluminum or wooden material.For a single casting or small batches of castings, we prefer to produce to use the wooden material to manufacture the mold to save money for customers. For other sand casting parts in large quantity, we prefer to use aluminum or iron to improve the mold’s service life.
2	Mold creation & assembly	The two shell halves are joined together and securely clamped to form the complete shell mold. If any cores are required, they are inserted prior to closing the mold. The shell mold is then placed into a flask and supported by a backing material.
3	Pouring	The mold is securely clamped together while the molten metal is poured from a ladle into the gating system and fills the mold cavity.
4	Cooling	After the mold has been filled, the molten metal is allowed to cool and solidify into the shape of the final castings.
5	Casting removal	After the molten metal has cooled, the mold can be broken and the casting removed. Trimming and cleaning processes are required to remove any excess metal from the feed system and any sand from the mold
6	Machining	CNC machining as per customer’s drawings.

Metal of travelling grate bars

Travelling grate bars are made from quality metal that guarantee long durability and extended lifetime. The metal used included cast iron, cast steel, stainless steel grate bars, heat resistant steel cast moving grate bars. Heat resistant cast iron grate bars, high-chcromium cast iron, Ni-hard cast iron grate bars can offer good wear and oxidation resistance. Stainless steel grate bar, such as AISI 310, 309 is mainly for corrosion and heat resistance.

Cast iron grate bars: HT200, HT250, RTSi5, ROTSi5, RTCr16, RTCr28, RTCr5, RTCr2Si4Mo, ZG40Cr24, etc. Heating resistant from 550-1200 °C

Heat resistant steel grate bars: DIN 1.4710, DIN 1.4729, DIN 1.4740, DIN 1.4743, DIN 1.4745, DIN 1.4776, DIN 1.4777, DIN 1.4823, DIN 1.4825, DIN 1.4826, DIN 1.4832, DIN 1.4849, DIN 1.4825, DIN 1.4849, DIN 1.4852, DIN 2.4778 heat resistant cast steel moving grate bars

Baoding Guokun also can customize metal chemical composition to meet your site’s fuel conditions.

Chemical composition of DIN 1.4743 or GX160CrSi18, heat resistant steel castings EN10295

C	Si	Cr	Ni	Mn	S	P	Mo
1.4-1.8	1.0 – 2.5	17-19	max 1.0	max 1.0	max 0.03	max 0.04	max 0.5

According to EN 10295, the heat tretament for “heat resistant steel castings” typically involves annealing at a temperature range of 800-850 °C, aiming for a hardness below 300HB, as this standard specifies the properties of heat resistant steel castings used in applications requiring high temperature resistance, often above 600 °C.

Baoding Guokun can manufacture and export large amount of moving grate bars for industrial boilers and waste to energy plants. Our grate bars are designed to maximize airflow while maintaining mechanical strength and shape in high temperature environments.
