Ethylene Cracking Furnace Anchor Anchors are mostly used as fixtures for integral linings (castable, plastic and sprayable linings). Refractory brick linings also use anchors, but they are not used in many occasions. Metal anchors are usually used to support and fix thin or heat-insulating integral linings, such as chimney linings, wear-resistant linings of petrochemical catalytic cracking reactors (usually tortoise shell mesh anchors), integral jet metallurgy The lining of the spray gun, the overall lining of the immersion pipe of the DH and RH vacuum degassing devices, the lining of the rotary kiln discharge day, the feeding port, etc. Metal anchors are mostly used to fix linings with a long-term use temperature below 1200 °C, or short-term use temperature above 1200 °C that can be used intermittently. Ceramic anchors are usually used to fix thicker (greater than 200mm) integral linings and are characterized by: Ethylene Cracking Furnace Anchor,Corbel Anchor,601 Inconel Refractory Anchor,310 Stainless Steel Refractory Anchor Puyu kiln technology (jiangsu) CO.,LTD , https://www.anchorpy.com

**DIN933 A2-70 Stainless Steel Hex Machine Bolt**
A machine bolt is a type of threaded fastener with an external male thread. It is often confused with screws due to their similar appearance, but bolts are typically used with nuts for secure fastening.
A hex cap screw features a hexagonal head and is designed to be tightened using a wrench or spanner. These screws are usually manufactured to stricter tolerances than hex bolts, which allows them to fit more precisely in certain applications. This means that while a hex cap screw can always be used where a hex bolt is installed, the opposite may not always be true.

(1) It can withstand higher operating temperatures, and is generally used in the lining of kilns that are used for a long time above 1200 °C;
(2) It can withstand the erosion and corrosion of corrosive atmosphere;
(3) It can be extended to the working surface to reduce the peeling of the overall lining;
(4) Compared with metal anchors, the contact area with the refractory lining is large, so it has a greater supporting capacity;
(5) The thermal expansion coefficient is equivalent to that of the overall refractory material, which can eliminate the cracking or peeling of the lining due to thermal expansion mismatch
