Abstract

A high-frequency coil provided with an auxiliary heating cylinder relates to the technical field of artificial lenses. A drawing hole or a chemical material hole (6) is formed in the middle of the high-frequency coil (3); a plurality of surrounding drawing holes (5) are formed outside the high-frequency coil (3); a plurality of drainage grooves (18) are formed in a radial shape from the drawing hole or the chemical material hole; a downwards recessed surface (9) is arranged in the middle of the upper surface of the high-frequency coil; an upwards recessed plane is arranged in the middle of the lower surface of the high-frequency coil; the outer end of one drainage groove (7) is communicated to the outer edge surface of the high-frequency coil through an opening (10); a cooling water way (14) surrounds the external of the high-frequency coil; a ground wire connection mechanism is arranged outside the high-frequency coil; the upper end of a tungsten or molybdenum cylinder (4) is connected with the external surface of the high-frequency coil; and an interval (17) is formed on the tungsten or molybdenum cylinder and corresponds to the opening. Through setting the tungsten or molybdenum cylinder with higher heat resistance at the lower part of the high-frequency coil, the quicker hot melting effect at the upper end of a raw material rod is obtained, and the hot melting speed at the upper end of the raw material rod is effectively quickened.

Description

Technical field

[0001] The invention relates to the technical field of artificial crystals, in particular to a high-frequency coil with an auxiliary heating cylinder.

Background technique

[0002] At present, the amount of silicon cores used in China is very large; in the existing process of producing silicon cores, single crystal silicon and other material crystal zone melting methods, most of them use a monocular high-frequency coil, and its working principle is: When working, pass high-frequency current to the high-frequency coil, so that the high-frequency coil generates current to inductively heat the raw material rod, and the upper end of the heated raw material rod forms a melting zone, and then inserts the seed crystal into the upper end of the raw material rod through the drawing hole Then slowly lift the seed crystal, the melted raw material will rise with the seed crystal to form a new columnar crystal, which is the finished product of silicon core or other ma...
