The main models of Sampler: F-type sampler, large and small head sampler, large straight cylinder sampler, and molten iron sampler.
① The head of the sand is formed by heating the coated sand.
② Assemble the cup box. The size of cup box is φ 34 × 12mm round or φ 34 × 40×12mm oval . After cleaning the cup box, the cup box is aligned and clamped with clips. Determine whether to place aluminum sheet, 1 piece or 2 pieces according to customer requirements. One aluminum sheet weighs 0.3g and two pieces weigh 0.6g.
③ Assemble sand head, cup box, quartz tube and iron cap. Apply glue on both sides of cup box and put it into the bare sand head, which is a mixture of talc powder and glass water. To check whether the adhesive is firm one by one, after the glue is slightly hard (at least 2 hours), put the sand head in turn to the assembled quartz tube and then pour the glue. Apply a circle of glass water to the sand head on the inner wall of slag retaining cap. It can be collected after being stationary for at least 10 hours. The slag retaining cap is marked with "Q" before the furnace and "H" mark after the furnace.
④ Assemble the sleeve. The paper pipe cut shall be flat and even to ensure the hardness and dryness. The length of the sleeve is 190mm and the inner diameter is 41.6mm. First, a liner with an inner diameter of 30mm is placed inside, which is 8cm long. The sleeve and liner are bonded with glass water. Press the sampler sand head into the casing to ensure that the sampler sand head is free of damage.
⑤ Assemble the tailpipe. Insert the tail pipe into the liner, fix the 3-layer paper pipe with gas nails, and the number of gas nails shall not be less than 3. Apply glue to the joint parts of tail pipe, liner and casing for one circle, and make sure to be even and full. Place the head down for at least 2 days before packing.
① Assemble the cup box. The size of cup box is φ 30 × 15mm. Clean the cup box, confirm whether aluminum sheet is needed according to the requirements. Firstly, align the cup box with tape, then place quartz tube (9 × 35mm) and small iron cap. Then, glue the quartz tube and iron cap with tape to ensure that no sundries enter the cup box.
② Put the combined cup box into the hot core box, make the sand head with coated sand, and wrap the cup box inside.
③ Assemble the sleeve. The paper pipe cut should be even, ensuring the hardness and dryness, and the inner diameter of the sleeve should be 39.7mm. The inner liner is 7cm long. The sand head is embedded in the casing for 10 mm. The big iron cap is glued well after dip in the glue. The glue is a mixture of talc powder and glass water to ensure that the glue is filled with a circle. Put the adhesive hard with the head up before assembling the tailpipe.
④ Assemble the tailpipe. Insert the tail pipe into the liner, fix the 3-layer paper pipe with gas nails, and the number of gas nails shall not be less than 3. Apply glue to the joint parts of tail pipe, liner and casing for one circle, and make sure to be even and full. Place the head down for at least 2 days before packing.
① The two steps are the same as the size head sampler, and the size of cup box is φ 30 × 15mm,
②Assemble the sleeve. The paper pipe cut shall be flat and even to ensure the hardness and dryness. The inner diameter of the sleeve is 35.7mm and the length is 800mm. The big iron cap is glued well after dip in the glue. The glue is a mixture of talc powder and glass water to ensure that the glue is filled with a circle. Place the head up to make sure the glue is hard before packing.
① The sand head is produced by coated sand, and a cavity is formed by two iron sheets for sampling. The iron inlet is sealed with tape to avoid the entry of sundries.
② Assemble the tailpipe, and insert the tail pipe in place, and it cannot be too loose after assembly. Fix the contact surface of tail pipe and sand head with gas nails, not less than 4, glue one circle at the joint part, and make it even and full. Place the head down for at least 2 days before packing.
