　　Aluminum foil fever piece which used in our daily life: aluminum foil fever piece in many cases will be used in place of heating metal materials, in daily life, be used to quickly are baking ingredients, such as rice cooker cooking; In manufacturing, for drinking water tank farms, petrol tank bottom heating, flat vulcanizing machine, plastic machinery and plastic device applications.

 

1. Aluminum foil fever films used for heating metal material has three ways:

 

(1) is immediately hair heat pipe casting or aluminum die casting in aluminum alloy metal materials.

 

(2) is the heat pipes with surface touch heating metal materials, such as with flat heat pipes sealed cater to a square or spherical surface heating stainless steel container.

 

(3) the mold shell, open holes in the casting parts and industrial machinery and equipment will Pierce hole heating, heating tube, such as plastic bag making machine heating tube.

 

2. The common casting hot plate surface temperature load and surface temperature:

 

1) aluminum casting hot plate surface load: 0.1 ~ 5 w/cm. (2) the surface temperature of 380 ℃ for the following application, 400 ℃ and higher temperature application can make the heating plate deformation and even cancer.

 

(3) cast iron heating plate aluminum casting hot plate surface load: 0.1 ~ 5 w/cm2, surface temperature of 700 ℃ and application;

 

3, copper hot plate aluminum casting hot plate surface load: 0.1 ~ 5 w/cm, surface temperature of 600 ℃ and application of high temperature 800 ℃.

 

3. The heating plate surface load and surface temperature of correlation: the heating tube made of copper in the copper alloy casting hot plate, through different surface load test to get the following results:

 

(1) surface load: 2 w/cm2, the surface temperature:

 

2, surface load: 2 w/cm2, the surface temperature: 330 ℃ and 3, surface load: 3 w/cm2, the surface temperature: 415 ℃.

 

4, surface load: 4 w/cm2, the surface temperature: 485 ℃ fluctuation, surface load: 5 w/cm2, the surface temperature: 550 ℃ in the experiment when insulation board up and down surface temperature of 500 degrees, the heating tube placed metal material internal heat is equal to electric heating material is in the air.

 

Heating tube placed in metal material heating, you required to master the following several aspects:

 

1. The metal sides are all hot;

 

2. The application of temperature control. Heating tube placed when heating surface temperature in the metal material is metal alloy products larger agree with operating temperature decision of heating tube raw material by larger agreed to operating temperature.
