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
CM SERIES VOLUMETRIC DOSER
Â
   CM series volumetric dosers are suitable for auto-proportional mixing of virgin materials, regrinds, master-batch or additives. Brusheless DC motors are adopted. According to the proportion and data set up, its micro-computer control system turns into referred speed, drive the precise SS304 dosing screw by the coupling, throw out the required material into injection machine. Its error value is below 1%. Give a total of six models with output ranging from 0.1~100kgs /hr. Double color dosers can be assembled from two single color dosers if required. Five components automatic mixing can be realized if customers adopt four color dosers.

Features:
* Dosing screws are chrome plated for durability.
* Unit is comprised of standard modules for ease of cleaning, disassembly and interchangeability.
* Blender is a standard equipment for double color doser to make the material evenly mixed, while also a optional equipment for single color doser to do so.
* Main material hopper is a standard equipment for double color doser. It is optional for single color doser.
* External signals can be directly interfaced with control box.
* The current operation mode can be recorded, unaffected by power failure so operation would be returned to normal when power is on.
* Forced material cleaning is convenient to replace masterbatch.
* Applicable on extrusion machines, just need to make a few wire replacements.
* Rotating speed can be automatically adjusted according to extruder processing speed, which maintains the fixed proportion of masterbatch.
* 50 units of parameter recipes are available for permanently recording the period of material discharging and finished products weight (for extruder, it is max. Throughput per minute).
* Use brushless DC motor and free from maintenance.
* Both master blockage and overload can be detected, then machine will halt and sound alarm.
* Based on customers demand, some mold cycles can be set to add additives periodically so that micro-metering can be achieved.Â

(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
