Product Brief

Product Brief

Dfc-600 type heat insulation covering agent for riser is a material with double functions of heat and heat preservation, which is used at the top of open riser. Its sensitivity is very high: after contacting with metal liquid in riser, dfc-600 type copper alloy heat insulation covering agent produces heat reaction, has a long heating time, and the heating time is up to 30min and expands gradually, which means that the density of heat insulation layer reduces to the initial value The density is less than half, thus forming a good insulation layer, so this product can greatly improve the feeding capacity of the riser. The appearance of the product is light black powder.

purpose

Purpose

A lot of heat loss is caused by heat radiation, heat conduction and heat convection at the top of open riser, which shortens the solidification time of riser and reduces the feeding efficiency of riser. In addition, the feeding capacity of the riser is further weakened because the metal crust at the top of the riser isolates the atmospheric pressure. After dissection, it can be seen that the shrinkage cavity of the riser without heating agent or with poor heating agent is like "carrot".

After dissection, it can be seen that the shrinkage cavity of the riser without heating agent or with poor heating agent is like "carrot".

After dfc-600 copper alloy heat insulation coating agent is applied to the top of open riser, it can form a low-density heat insulation layer, which can prevent or largely reduce the heat radiation, heat conduction and heat convection, and also avoid premature crust on the top of riser. After the riser was dissected, the pores were like the bottom of a pan.

Dfc-600 copper alloy heat insulation covering agent has the following advantages:

Dfc-600 copper alloy heat insulation covering agent has the following advantages:

Low dosage: dfc-600 is only half of the general heating material because of its unique expansion characteristics. So its performance price ratio is very high.

2. When the liquid metal is poured to the upper end of the riser sleeve, the product shall be added immediately according to the reference dosage provided in the table below, and the heating agent shall be leveled to make the thickness uniform. Adding too late or using too little will reduce feeding efficiency of riser.
