China Supply square type carbon cup With Good Quality

The carbon cups are used matching with the carbon and sulphur analyzer to quickly analyze carbon content, silicon content and carbon equivalent in molten iron, which can save smelting time of molten iron, greatly reduce production cycle of white and grey cast iron and therefore increase production efficiency.

Principle of measurement: Collection of temperature curves is conducted by microprocessor. Contents of carbon and silicon, and quality of molten iron can be calculated by crystallization process of molten iron.

Temperature range: 1250℃～1370℃

Measuring range: carbon equivalent 2.5～5.0±0.047%

Carbon content 2.1～4.2±0.039%

Silicon content 0～20±0.1%

Graduation No. of supporting thermocouple wires: K type

Shape of carbon cup: round type

Measurement function: thermal analysis towards cast iron

Measuring time: 240 seconds at most

Indication in working process: the carbon cup is connected with three signal indicators on the panel of “Ready”, “Measurement” and “Finish” through potential free reed relay.

Method of application:

1. Make the carbon cup put in the cup base with the positive and negative electrode correctly installed, when the green light on the carbon and silicon analyzer is on.

2. Make a spoon of clean molten iron in carbon cup. It is better to make sure temperature of molten iron is 50-100 ℃ higher than liquidus temperature. If temperature of molten iron is too low, liquidus temperature cannot be measured; if temperature of molten iron is too high, it is likely to fuse the thermocouple wire. It is required that injected amount of molten iron is nearly 90-100% of the carbon cup. If injected amount is too little, temperature platform will become steep and thus correct feature points cannot be recognized; if injected amount is too much, molten iron will spill out, additives in carbon cups measuring components and performance of molten iron will lose and thus the carbon cup will not work. At this time, green light on the carbon and silicon analyzer is off and yellow light is on.

3. In about 4 minutes, yellow light is off, red light is on, measurement finishes and measured data will be shown on the screen and in the meantime analytical data can be printed. After once measurement, the carbon cup used should be taken down as soon as possible, which can avoid temperature rise of the cup base influences subsequent measurement accuracy.
